    <p>Display the video stream from <code>getUserMedia()</code> in a video
    element and control exposureMode, exposureTime and exposureCompensation if camera supports it.</p>

    <p>The <code>MediaStreamTrack</code> object <code>track</code> is in
        global scope, so you can inspect it from the console.</p>
